IMPROVEMENT IN MACHINES FOR JOINTING STAVES.

Specification forming part of Letters Patent No. 55,238, dated June 5,186B.

' Sipesville, Somerset county, in the State of Pennsylvania, haveinvented a newr and Improved Stave-Holder; and I do hereby declare thatthe following is a full and exact description thereof, reference beinghad to the accompanyin g drawings, and to the letters of reference madethereon.

The nature of my invention consists in two upright posts formingholding-gages, the edge next to the stave being an arc of a circle, andhaving three setting-screws in each, by means of which a true beveledjoint for a vessel of any circumference, from a keeler to a barrel, maybe made.

It is operated by placing' the holderon ajoint-plane, adj Listing the setting-screws B B B to make the bevelto suit the circumference of the vessel required, then placing a staveagainst the gage-holder, pressing it closely to the lower corner (markedO) with the thumb when the gage is on the right side of the plane, andwith the ngers when on the left, and holding the stave and pressing iton the plane-bit with the other hand. The holder and stave are thenpushed over the plane in the. manner indicated on the diagram. The halfof one side of the stave is thus jointed. The stave is then ended andthe half of the other sidejointed in a similar Way.

Tojoint the sides of the other end the jointer is turned around, so asto put the gages on the left side of the plane, after which the process
